Ignition problem? When did you tune up your ignition system last time? Spark plugs, wires, cap, rotor maybe coil as well.

In most of the cases tach fluttering are caused by a bad ignition system. The speedo could be the same, but it could be something else as well. Tune up the ignition first, then we will see.

HTH,

My Tach keeps fluttering What causes this? Telltale Ignition problems. Do tune up with the above listed products.

See the SyTy FaQ and go through your ignition... again.
